Research, development and application of three-phase fluidized beds, especially those involving solids fluidized by an upward concurrent flow of gas and liquid, have culminated in the recognition of three-phase fluidization as a mature technology. However, a rational model for predicting minimum fluidization velocities of comparable reliability to those available for conventional two-phase fluidized beds has not yet been developed. Hence, in this paper, two mathematical models are developed to predict the minimum liquid fluidization velocity of a bed of solid particles in the presence of a fixed concurrent gas velocity. Both models start with the Ergun equation for single phase flow through a buoyed weight of the bed.
